Frequently Asked Questions

Which voltage should I choose: 5V, 12V, or 24V?
Choose 5V for compact, short-run installations with 10 mm cutting. Choose 12V for standard constant-voltage projects with 10 mm cutting. Choose 24V when you prefer 20 mm cutting and higher power options on wider PCBs (4/5 mm).
Which PCB width is best for my profile: 2.7mm, 3mm, 4mm, or 5mm?
2.7mm / 3mm are ideal for ultra-slim channels and tight spaces. 4mm balances slim fit and broader profile compatibility. 5mm is the most universal option for narrow profiles and easier installation.
Can I cut the strip, and how do I cut it correctly?
Yes. Cut only at the marked cutting points. Cutting intervals are 10 mm (5V/12V) and 20 mm (24V). Always match the driver voltage to the strip and use proper connectors or soldering after cutting.

Application

The LUMSET® Ultra-Narrow COB Strip (400 LEDs/m, CRI90+) is built for precision linear lighting where space is limited and a clean, dot-free light line matters. The 2.7mm / 3mm options fit ultra-slim channels for showcases, under-cabinet task lighting, shelf accents, jewelry displays, and fine decorative outlines. The 4mm / 5mm options offer broader profile compatibility for cove lighting, cabinet contours, signage edges, and architectural detail lines. With CCT options up to 6500K and high color rendering, it’s ideal for residential, retail, and hospitality projects that require smooth, premium-looking illumination.
